Weight loss involves reducing body weight, typically through a combination of diet, exercise, and lifestyle changes. It aims to improve health, enhance fitness, and reduce the risk of chronic diseases. Effective weight loss strategies include consuming a balanced diet rich in fruits, vegetables, lean proteins, and whole grains while minimizing processed foods and sugary beverages. Regular physical activity, such as walking, running, or strength training, helps burn calories and build muscle. Sustainable weight loss emphasizes gradual progress, setting realistic goals, and maintaining healthy habits long-term, rather than relying on quick fixes or fad diets.
